SMOKE-WASHER.

Specification of Letters Patent.

Patented Dec. 31, 1918.

Application filed March 1, 1918. Serial No. 219,929.

To all whom it may concern:

Be it known that I, RICHARD J JOHNSON, a citizen of the United States,residing at Lake Benton, in the county of Lincoln and State ofMinnesota, have invented certain new and useful Improvements in Smoke-)Vashers, of which the following is a specification.

This invention relates to smoke washers which may be used in connectionwith any source of smoke supply, such as asmoke stack.

The object of the invention is to provide a simple and efiicientapparatus of this character which will thoroughly mix'and dissolve theproducts of combustion in water and then discharge the water into asewer or other suitable place of deposit where it will be harmless.

Another object is to provide an improved mixer or washer of thischaracter whereby the smoke and other combustion products dischargedthereinto will be effectively agitated and commingled with watercontained therein.

With the foregoing and other objects in view, which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterclescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed may be made within thescope of what is claimed without departing from the spirit of theinvention.

In the accompanying drawings 2- Figure 1 represents a vertical sectionof a washer constructed in accordance with this invention.

Fig. 2 is a horizontal section taken 011 the line 2-2 of Fig. 1, and

Fig. 3 is a similar view 33 of Fig. 1.

In the'embodiment illustrated, the apparatus constituting this inventionmay be connected with any source of smoke supply (not shown), such as aboiler or other furnace smoke stack.

The apparatus constituting this invention comprises a closed casing 1having a discharge outlet l at its upper end which is designed to beconnected with a pipe (not shown), which conveys the water and theunaffected gases discharged through the easing to a sewer or othersuitable place of deposit.

taken on the line A pipe 2 enters the washer or mixing casing 1 throughthe top thereof and extends to a point near its bottom where it isprovided with lateral oppositely disposed extensions 8 and 4 havingupturned mouths 5 through which the products of combustion enteringthrough pipe 2 are designed to be discharged.

Revolubly mounted on the end of the pipe 2 which is disposed within themixer is an agitator in the form of a plurality of reticulated vanes 6which radiate through collars 7 and 8 revolubly mounted on said pipe end2. Any desired number of these vanes 6 may be employed, four beingpreferably used, and the mouths 5 of the pipe extensions 3 and 4 aredisposed adjacent the lower ends of said vanes and are designed todischarge their contents in the path of the vanes so that therevolutions thereof will operate to thoroughly commingle the products sodischarged with the water contained in the mixer.

A bevel gear 9 is fixed to the collar 7 and meshes with a bevel pinion11 carried by a shaft 10 which extends laterally through one side wallof casing l as shown clearly in Fig. 3 and by means of which motion isimparted to the mixing vanes. Motion is imparted to this shaft 10 by anysuitable means (not shown).

A water supply pipe 12 enters the casing 1 at the lower end thereof andis connected at its other end with any suitable source of supply (notshown), so that water may be continuously supplied to the casing 1, en-

tering at the bottom thereof and overflowing at the top through pipe 1.

In the operation of this apparatus, motion being imparted to shaft 10 bya source of power (not shown), will cause the vanes 6 to rotate withincasing 1 and the products of combustion entering through pipe 2 will bethoroughly commingled by the revolutions of said vanes with the water inthe casing 1. WVhen these products of combustion have been thoroughlycommingled and dissolved in the water of the mixer they pass out withthe water through pipe 1 to a suitable place of deposit.

From the foregoing description, taken in connection with theaccompanying drawings, the advantages of the construction and of themethod of operation will be readily apparent to those skilled in the artto which the invention appertains and while I have an outlet at itsupper end,

' combustion thereto, said pipe describedvthe principle of operation ofthe understood that against which the contents of said pipe are Idischarged. 7

2. In a smoke washer, a closed water containing mixing chamber having aninlet at its lower end and an outlet at its upper'end,

a pipe extending into said chamber through Copies of this. patent may beobtained for five cents each, by addressingthe the best embodimentillustrative and the top to a point near its bottom, said pipe havinglateral extensions provided with upturned mouths, and'a plurality ofagitator vanes revolubly mounted on said pipe above said mouths andagainst which the contents of said pipe are discharged,

3. An apparatus of the class described including aclosedcasing having anoutlet pipe at its upper end and adapted to contain a washing fluid, asmoke pipe extending'into said casing through the top thereof andprovided at its lower end with laterally extending branch pipes havingupturned mouths at their free ends, ed to rotate on said pipe above saidmouths, and means for actuating said agitators.

In testimony whereof I aflix my signa ture in presence of two witnesses.
